DOOR CONSTRUCTION FOR RAILWAY-CARS.

Application filed July 23, 1915.

Z '0 all whom 2'25 may concern Be it known that I, HENRY J. TIERNEY, acitizen of the United States, residing at Denison, in the county ofGrayson and State of Texas, have invented certain new and usefulImprovements in Door Constructions for Railway-Cars, of which thefollowing is a specification.

My invention relates to the construction of railway cars, and moreparticularly to door constructions for box cars.

One of the objects of the invention is to provide a novel and improvedform of out side door which will be grain-tight so that when the car isloaded with grain no supplementary grain door will be required.

A further object is to provide a door which, instead of being supportedoutside of the wall of the car, on hangers for example, is arranged tomove back and forth across the door opening in a plane within theplaneof the outside of the car wall, thereby eliminating all hangers,brackets and other proj ecting members likely to become broken off orinjured, insuring that the door be reliably supported on the car at alltimes, whether closed or open, and making it possible by means ofcertain devices which will be hereinafter described, to so engage thedoor with the door frame, when the door is closed, that a grain-tightfit will be made.

A further object of the invention is to provide a construction in whichthe door,

when opened, is moved between the inner and outer sheathing of the carwall.

A further object is to provide a car door with a novel and improved formof supplemental or relief door, adapted to be used when the car isloaded with grain, which may be readily opened to relieve the pres sureof the grain against the main door even when the pressure isconsiderable.

A further object of the invention is to provide certain novel means forforcing the door, when closed, outwardly against the door frame so thatthe door will be waterproof and grain-tight.

The invention has for further objects such Specification of LettersPatent.

Patented Oct. 31, 1916.

Serial No. 41,565.

other new and improved constructions, arrangements and devices relatingto car door constructions as will be hereinafter described and claimed.

The invention is illustrated, in a preferred embodiment, in theaccompanying drawings, wherein Figure 1 is a fragmentary side elevationof the superstructure of a box car showing the. side door of the car andadjacent parts constructed in accordance with the principles of myinvention. Figs. 2, 3 and 4 are sectional views taken on lines 2-2, 3+3and 44, respectively, of Fig. 1. Fig. 5 is an enlarged fragmentary planview in the same plane as Fig. 4. Fig. 6 is a fragmentary elevation,taken from within the car to show particularly the rear edge of thedoor, when the door is in closed position, and the parts of the caradjacent thereto. Fig. 7 is a fragmentary sectional view on line 77 ofFig.1. Fig. 8 is a plan view, and Fig. 9 a view, in perspective of acasting employed for holding in proper position the double door post atthe rear edge of the door opens ing, together with certain otherstructural parts of the car. Fig. 10 is a view, in perspective, and Fig.11 a sectional view, illustrating the corresponding casting at the lowerend of said double door post. Fig. 12 is a view, in elevation, of one ofthe door rollers and its housing. Fig. 13 is a sectional view, on anenlarged scale, taken on line 13-13 of Fig. 1,,and Fig. 1 1 is asectional plan on line 1414 of Fig. 13.

Like characters of reference designate like parts in the several figuresof the drawings.

25 designates one of the side plates of the car, 26 thecorresponding'side sill, 27 the flooring of the car, and 28 the roof.The side wall of the car is made up of the usual vertical posts, one ofwhich is shown at 29, and outer sheathing boards 30 and inner sheathing31. In the portion of the side wall to the rear of the door opening,that is, in the direction from the door opening in which the door ismoved when opened, the usual diagonal strut is omitted and in placethereof there is a pair of such struts 32, 32 which are spaced apart.This section of the wall, therefore, provides a recess 33 for the doorwhen opened. The door slides through a double door post or pair of posts34, 35.

36 designates the post at the forward side of the door frame.

The door is composed preferably of an inner metal plate 37, an outermetal plate 38, and a filler 39 preferably of wood, the parts beingsecured together by rivets 40. One of the plates, the plate 38 forexample, is formed at the forward and rearedges of the door with angularflanges 41, 42 which sheath the edges of the filler. The back plate 37is formed with a similar flange 43 which sheaths the top edge of thefiller. A Z-bar 45 is arranged at the bottom of the door, the lowervertical leg 46 of which projects back of the threshold plate 47 andbetween the same and a number of curved guide shoes 48 which are securedto the floor of the car just within the threshold plate. The horizontalflange 49 of the Z bar is formed with slots through which projectrollers 50, the axles 51 of which are carried in housing members 52secured to the Z bar. The threshold plate 47 is bolted to the flooring27 of the car by bolts 53 which extend through a threshold extensiontimber 54 arranged outside of the side sill 26. The threshold plate isformed with an extension 55 which lies within the door recess betweenthe inner and outer sheathing providing a track for rollers 50 when thedoor is moved in and out of the recess. Except at the places where theroller housings 52 are attached to the Z bar the lower edge of the innerplate 37 of the door is flanged over and attached to the horizontalflange 49 of the Z bar as indicated at 56 (Figs. 2 and 3.) The upperedge of the door. is guidedin a guide slot 57 formed between the sideplate 25, a timber 58 bolted to the side plate on the outside thereof,and a strip 59 secured to the under side of the side plate. The forwardedge of the door enters a groove 60 formed in the forward door post 36.A locking device, indicated generally at 61, is employed for holdingthedoor in the closed position. This device is not described in detailas it is the subject matter of a co-pending application filed by me onthe 23rd day of July, A. D. 1915, Serial No. 41,566.

The rear door posts 34, 35, are preferably supported at the bottom andheld in proper spaced relation by means of a casting 62 (Figs. 10 and11), resting upon and secured to the side sill 26 by bolts 63 and formedwith a socket 64 for the outer post 34 and a socket 65 for the innerpost 35. The casting is preferably formed also with a bracket 66 whichsupports the end of the threshold extension timber 54' above referredto. The

upper ends of the posts 34, 35 extend into sockets 67, 68 of a casting69 (Figs. 8 and 9) secured by bolts 70 to the side plate 25 (Fig. 6).The casting 69 is formed also with a pair of sockets 71 to receive theends of the diagonal strut members 32.

In order that access may be had to the door recess 33 in the side wallof the car, the lower inner sheathing board 31 is hinged to the boarddirectly above it. lVith the car loaded with grain it is possible thatthe recess might otherwise become so clogged that s the door could notbe conveniently opened.

Arranged at the rear edge of the door is a curved cam shoe 72 whichpreferably extends from the top to the bottom of the door opening and issupported by means of bracket castings 73 on a rod 74, the upper end ofwhich turns in a bracket 75 formed on casting 69, the lower endextending through the sill 26 and being provided with a handle 76. Theshoe, when turnedinto its operative position, engages the door and alsothe inner rear door post 35, which is pro vided for that purpose with awear strip 77, and serves the double purpose of forcing the dooroutwardly against the door frame and closing the space between the rearedge of the door and the inner rear door post 35. By this arrangementthe door construction is waterproof and grain-tight. Preferably a springlatch 78 is secured to the under side of the sill 26 which is so shapedand positioned that the handle 76 will pass under the same when the shoeis turned to its operative position, the latch preventing an accidentalreverse movement of the handle. Its elasticity permits it to yield,however, with a sufficiently strong pull on the handle.

With a view to the employment of the car as a grain carrier, without asupplemental grain door, the door above described is provided with anupper small door 79 for loading the grain into the car and a lower door80 which may be opened to sufficiently relieve the pressure of grainagainst the door, when unloading, to permit the main door to be slidback. The main door is formed with a recess 81 for the upper door 79,the metal plates forming the door being flanged over the edges of thewood filler around the door opening, as indicated at 82, 83. The flanges82, 83 are formed at the rear side of the door opening with lips 84, 85which are perforated for a seal pin 86, the latter extending through aperforation in the rear edge of the small door 79. The pin 86 is formedwith a slot 87 and the lip 84 with a slot 88, which slots are adapted toreceive any ordinary type of car seal. The lower small door 80 is ofsimilar construction and when opened enters a recess 89 in the main door(Fig. 3). At the inner end of the recess 89 is an opening 90 whichextends down through the bottom of the door, the purpose of this beingto permit grain or other obstructions to escape from the door recess,thereby preventing the opening of the small door 80 from beinginterfered with.

Set into the forward edge of the main door so as to be substantiallyflush therewith are hand grips 91.

WVhen the car is used for carrying grain the grain will be loaded intothe car through the upper opening in the door. In unloading the lowersmall door 80 is slid back into the recess 89 in the main door. Thesmall door can be moved quite readily even though the pressure of grainagainst 'it is considerable because it is moved not against the grainbut into the recess formed for it in the main door. When the pressure ofthe grain against the main door has been somewhat relieved in thismanner the shoe 72 may be turned by handle 76 so that the rear edge ofthe main door is freed. The main door can then be slid back into itsrecess in the car w all. With the upper edge of the door engaged in theslot 57, the forward edge in slot (30, the lower edge-flange 48 of theZ-bar against the threshold plate 47, and the rear edge pressed againstthe outside post member 34L by the shoe 72, the action of which is, ofcourse, to force the entire door against the door frame, an engagementis provided as between the door and the car which is waterproof andgrain-tight.

A car equipped with a door of this sort may be used without anyadjustment or changes for carrying ordinary merchandise as well asgrain. When carrying grain no supplemental grain door is necessary. Theconstruction, it will be seen, presents no projecting parts likely to bedamaged by side swiping. The door itself is within the plane outside ofthe sheathing of the car when in closed position. l/Vhen opened forlading the door is completely housed within the wall of the car so thatit cannot be damaged either from the outside, for instance, by a draybacking up against it, which happens not infrequently with the ordinaryhanging outside door, or from within by careless handling of the cargo.The reliability of the door does not depend upon hangers. It issupported on a track laid on the floor of the car.

' Although the several improvements above described cooperate one withthe other to provide a door having the advantages indicated, it may bepossible tov utilize certain of said improvements singly or with lessthan all of the other constructions forming the invention in itspreferred embodiment. Certain modifications in the form and constructionof the parts might also be devised. For these reasons I do not wish tolimit the invention to the precise constructions, de-
